Putting the border in place: customs regulation in the making of the Irish border, 1921–1945

This paper explores the historical geography of the making of the Irish border through a focus on the practices of customs regulation through which it was constituted and on the impeded, permitted and concealed mobilities of people and objects across the customs boundary after 1923. It traces how legislative change at the level of the state – in this case the governments of the Irish Free State, Northern Ireland and the United Kingdom – was translated into the routine practices of those trying to regulate the movement of people and objects across the customs boundary, and considers the responses of those subject to, and regularly subverting, these efforts. Drawing on recent interests in the prosaic practices of the state, and in materiality and mobility more widely, our focus is both on the work of political power at the border through the practices, texts, tools and techniques of customs regulation, and on the experience and effects of customs control for those living near the newly defined line between Northern Ireland and the Irish Free State.
